Abstract
The invention discloses a gas-fat-doped coking and coal blending method. The gas-fat-doped coking and coal blending method comprises the following steps: firstly, determining the Giseeler fluidity of gas-fat coal to obtain a maximum fluidity MF, and determining a Hoya expansion value b; marking the gas-fat coal with the Hoya expansion value b being greater than 150 percent or the maximum fluidity MF being greater than 70000ddpm as No.1 gas-fat coal; marking gas-fat coal with the Hoya expansion value b being not greater than 150 percent or the maximum fluidity MF being not greater than 70000ddpm as No.2 gas-fat coal; then blending the gat-fat coal according to the following mass percentage: 5-10 percent of No.1 coal, 0-15 percent of fat coal, 20-30 percent of coking coal, 0-5 percent of No.2 gas-fat coal, 35-45 percent of coaling coal and 10-15 percent of lean coal; and enabling the mass standard of the blending coal to meet the conditions that the volatile component is 26-28 percent, the ash content is less than 10 percent, the Hoya expansion value b is -6 to 10 percent and the softening temperature is 375-385DEG C. The coal blending and coking can be carried out according to the gas-fat-doped coking and coal blending method, so that the quality of coke can be effectively improved, the coat blending cost is reduced and the strength of the coke obtained by coking is high.
Description
Technical field
The invention belongs to the coke making and coal blending technical field, be specifically related to the coke making and coal blending method that a kind of gas-fat coal is participated in.
Background technology
Gas-fat coal belongs to a kind of of bituminous coal, and its criteria for classifying is a leading indicator with volatile matter and plastometer indices, and inferior turgidity difficult to understand is an auxiliary characteristics.Because ore deposit point is different, the coal seam is different, and the coal yard pilling up time is different, and each gas-fat coal ature of coal differs greatly.The gas-fat coal plastic mass that has is abundant, and the plastic mass turgidity is high, good fluidity, its deflection rich coal character; Though the gas-fat coal plastic mass that has reaches the gas-fat coal criteria for classification, the plastic mass turgidity is low, mobile not enough, and plastic mass is second-rate, its ature of coal deflection bottle coal character.Therefore, further do not analyze the ature of coal characteristic and the corresponding blending method that improves of gas-fat coal, just mechanically carry out coal-blending coking, quality that greatly influences coke and stability according to experience.
Summary of the invention
Technical problem to be solved by this invention provides the coke making and coal blending method that a kind of gas-fat coal is participated in, and this method can rationally be utilized gas-fat coal resource, the coke quality steady that coal-blending coking makes, better performances.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the Giseeler fluidity of measuring gas-fat coal is to obtain maximum fluidity MF and to measure inferior turgidity b value difficult to understand; With the inferior turgidity b value of Austria>150% or maximum fluidity MF the gas-fat coal of 70000ddpm is designated as gas-fat coal 1#; The gas-fat coal of the inferior turgidity b value of Austria≤150% and maximum fluidity MF≤70000ddpm is designated as gas-fat coal 2#, then gas-fat coal is pressed following mass percent coal blending: gas-fat coal 1#:5 ~ 10%; Rich coal 0 ~ 15%; 1/3 coking coal: 20 ~ 30%; Gas-fat coal 2#:0 ~ 5%; Coking coal: 35 ~ 45%; Lean coal: 10 ~ 15%, and the quality index of mixed coal is satisfied: volatile matter 26 ~ 28%, < 10%, inferior turgidity b value difficult to understand is-6 ~ 10% to ash content, 375 ~ 385 ℃ of softening temperatures.
The present invention is on the basis of Chinese Coal Classification standard; In conjunction with maximum fluidity MF and Ao Ya turgidity b value gas-fat coal is further segmented; With the inferior turgidity b value of Austria>150% or maximum fluidity MF the gas-fat coal of 70000ddpm uses as the high-quality gas-fat coal; The gas-fat coal of the inferior turgidity b value of Austria≤150% and maximum fluidity MF≤70000ddpm is used as high volatile 1/3 coking coal; And combine to the quality index of mixed coal particularly the difficult to understand inferior turgidity b value of mixed coal control, each coke-oven plant is joined less or the situation that is unworthy of gas-fat coal is improved, and carry out coal-blending coking according to the method described above; Can effectively improve coke quality, reduce coal blending cost.Coking on the coke oven more than the 4m, producing the gained coke strenth can reach: shatter strength M40>=80%, M10≤7.0%, reactive (CRI)≤28.0%, post-reaction strength (CSR)>=62.0%.
